3. LeAnn Rimes
LeAnn Rimes recently copped to feeling guilty and disgusted with herself over her double-marriage-ending affair with Eddie Cibrian in 2009. {relatedarticles}At the time, however, the young actress/singer appeared to have no regrets about publicly hooking up with the married actor while she herself was hitched to Dean Sheremet. Cibrian and Rimes have since wed, but the world may forever sit in judgment of Rimes' previous indiscretions.
